deepdiff比较两个json文件数据差异性

Python代码片：

import json
import sysfrom deepdiff import DeepDiff
from deepdiff import grep, DeepSearch
from deepdiff import DeepHash# print(DeepDiff("abc", "abcd", ignore_order=True))class CompareJson:"""比较两个json格式的数据文件"""def read_json(self, filename):'''读取json格式的数据'''try:with open(filename, 'r', encoding='utf-8') as fileHandle:text = fileHandle.read()return json.loads(text)except IOError as e:print("Read file Error:" + e)sys.exit()# 1、type_changes：类型改变的key# 2、values_changed：值发生变化的key# 3、dictionary_item_added：字典key添加# 4、dictionary_item_removed：字段key删除# exclude_paths 排除指定的字段# ignore_order 排序时忽略@staticmethoddef diff_json(filename1, filename2):d_dict = DeepDiff(CompareJson().read_json(filename1),CompareJson().read_json(filename2), ignore_order=True)if d_dict == {}:print("两个文件内容一致")for k, v in d_dict.items():if k == "type_changes":print("类型改变的key:", v)elif k == "values_changed":print("值发生变化的key:", v)elif k == "dictionary_item_added":print("字典key添加:", v)elif k == "dictionary_item_removed":print("字段key删除:", v)CompareJson.diff_json("../file/no1.json", "../file/no2.json")
